kallsyms_lookup which in turn calls for kallsyms_lookup_buildid() writes on index "KSYM_NAME_LEN - 1". Thus array size should be KSYM_NAME_LEN. for powerpc and hexagon it was defined as "128" directly. and commit '61968dbc2d5d' changed define value to 512, So both were missed to update with new size. Fixes: 61968dbc2d5d("kallsyms: increase maximum kernel symbol length to 512") Signed-off-by: Maninder Singh <maninder1.s@samsung.com> --- arch/hexagon/kernel/traps.c | 2 +- arch/powerpc/xmon/xmon.c | 2 +- 2 files changed, 2 insertions(+), 2 deletions(-)
